Made some changes to the menu
Removed the admin modal overlay
Made btn classes btn-large
Added a minimum for the iFrame.
Implemented a "Continue" button to control for mouse position.
Added a backgroundIsVisible assignment on crossing (prevents the black boxes from appearing on a fast cross).
Added a patch to a bug where html2canvas caused scroll to the top. See (https://github.com/niklasvh/html2canvas/issues/57). Hopefully, this is stable enough, as we just force it to scroll back to the original position.
